[BattleRifleG3]

Yes, I've posted on this before. But I'm still looking for input from people who have experience with the FAL (as I've never owned one, chose a G3 instead).

What I'm not sure about is whether it would be more economical to rebore an existing FAL barrel or to have one custom made. And then I have to ask whether the barrel would be strong enough after reboring as it would be thinner.

I assume chamber pressures would be the same as 308 Winchester, being based off of the same case. The pressure would drop more rapidly as the volume of the gas in the wider bore would be greater than 308.

However, with the same chamber pressure but an increased cross sectional area, the force on the bolt, and thus against the receiver would be 35% greater than with a 308 caliber bore. Would the FAL bolt and receiver hold up to this increased stress?

I figured this would use an 18" or 16" barrel, as the wider bullets would accelerate faster and have less use for a longer barrel.

Any thoughts from people who know FALs?
